Hello,
there is a bug with parameter passing in nested subcircuits.
It is not limited to the netlist form, but to provide the minimal problem I have used the netlist below.
For the problem see the comment below.
.subckt top params: V=1
V1 1 0 {V}
.ends top
.subckt sub params: V=1
* passing parameter, working ok
V1 1 0 {V}
.subckt nested params: V=1
V1 1 0 {V}
.ends nested
* top level with parameter passing, working ok
X1 top params: V={V}
* nested with default parameter, working ok
X2 nested
* nested with fixed parameter, working ok
X3 nested params: V=2
***************************************************
********************bug in LTspice********************
* QSPICE has no problems with that (but other problems)
***************************************************
* nested with parameter passing, not working ok
* => WARNING: Can't resolve .param v=v
X4 nested params: V={V}
***************************************************
.ends sub
.op
X1 sub params: V=1
I tested it with QSPICE also and it has no problem here (but another).
